The present invention relates .to calculating v machines and particularly to machines of the accounting-or bookkeeping type which are provided with a traveling paper carriage for supporting the bookkeeping forms and also for automatically controlling the various functions of the machine in accordance with the columnar positioning thereof. 7

This application isa division of the United States patent application of Rayond A. Christian et' al., Serial No. 790,032, filed December 6, 1947, now Patent No. 2,626,749, issued January 27,

In the business world of today, there are nearly as many different types of bookkeeping systems employed as there are separate business orgamzations. It has, therefore, been necessary-for the builders of bookkeepingor accounting machines to modify the designs of their machines frequently in order to adapt them to the particular bookkeeping system employed by the These so-called customer order machines are costly to build, since certain portions of the machine must be practically hand-made in order to furnish amachine having the desired characteristics. Accordingly, it is an object of the present invention to provide a solution to this problem of adapting a particular type of accounting machine to fit the bookkeeping system utilized by any particular cus- This has been done in the present instance by designing an accounting or bookkeeping machine which is sufficiently flexible in character that it may be used in connection with practically any ofthe complex accounting systems used bypresent-day business establish mentsa Another problem confronting both themanufacturers and the users of accounting machines is the complexity of many.of our present bookkeeping systems. Not only is it diflicult to construct' machines which are capable of performing the many and complicated operations involvedjbut it is also dimcult for the operator of the machine to. learn how to manipulate the various controls of the machineso as to properly perform the various operations involved in making an entrygon the books. It is, therefore, a further object of the invention to provide a bookkeeping machine which will perform most of these operations automatically and therefore require a minimum amount of time and attention on the part of the operator of the machine.

' 'A further object of the invention resides in the provision of a simplified type of, front-feed papercarriage. carriage is driven both a hydraulic drive mechanism which is operated by the same motor which serves to drive the main operating mechanism of the machine.

Another object of the invention resides in the provision of novel means for controlling the various functions of the machine either from the traveling paper carriage, from the several motor bars for initiating cycles of operation of the machine, or from certain of the manipulative keys situated on the keyboard of the machine.

A further object of the invention is to provide a plurality of slides operating under the control of various controlling devices for controlling certain functions of the machine. Ehis control mechanism is designed in such a manner that any of the controlling devices may be arranged to stop any of the slides in any of their various positions, thereby aiiordingthe maximum amount of flexibility in thecontrol of the machine by this mechanism.

Still a further object of the invention residesin the provision of an improved means for controlling the tabulating movements of the paper carriage, said means being .under the control either of a groupof manually-operable keys, of the several motor bars for initiating cycles of operation of the machine, or of the papercarriage itself. I Y

Still another object of this invention resides in the provision of novel means for enabling the carriage to be selectively tabulated in either a forward direction or a reverse direction to various columnar positions and alsoin the provision of means for enabling the foregoing means to be controlled by the carriage.

With these and other objects in view which will become apparent from the following description, the invention includes certain novel features of design and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the. drawings which ac company and form apart of this specification.

Reference is also made to application Serial No."524,846,"f1led"March 3, 1944, now Patent No. 2,442,402, issued June 1, 1948,to John T.- Davidson et a1., and entitled Accounting Machines, for a'further disclosure of certain of the features incorporated in'themachine to be de- "scribed hereinafter.

"The' basic structureof the present machine is patterned 'after the machine shown in. the foregoing-patents, which has: been on the market ioeman years. "For example, the construction and'arrang'ement of 'the'keyboard, the differential actuatorsE'the printed, and the totalizers are practically identical with the corresponding mechanisms-shown in. thepatents. The basic structure of the. prior: art machine is disclosed in the Ellis Patent No. 1,197,276, while an addsubstract totalizer of'the. same. general tvpeas that-used in: the. present machine is: disclosed in Ellis Patent No: 11,203,863. The totalizer engag inc-and; disengagingmechanism; on the. other hand, is shown ini the. above mentioned Patent 'No. 2,442,402. Most'of the mechanisms for controlling the various machine functions, however, are-new in the sub jc'ct' machine, as are also the papei carriage and the controlling mechanisms therefor. "In: addition,- the'instantmachine is equippecl 'with an electric typewriter, which: is drivenby the same motor that operates the remainder of: the'machinc; With this brief: over all descr? ticn in mind, the various parts of the machine will-now be. described: in; detail; so as to provide a full and:- complete understanding of theentire device;

2.j-Gc7te 2%dZ. crgameanomnd cabinet (Fig'm'e 35) A perspectiveview; of thel machine as a whole is-shown: in. Figure: of the drawings,-.-and a. general'. understanding of; the/layout and organizationof: the machine: may; be obtained fromthis illustra-tiom: As:showrrherein-, a typewriter keyboard-J is:located-at .theefront; end oi the machine, wh-ilei'justbehindtandrsomewhat abovethiskeyboard is an amount keyboard, on which may be set up the various amounts which are to beentered in the, accounting machine. To the left of theamount keyboard is acontrol keyboard; containing the various function control keys. while to the right of it are located a plurality of motor bars and carriage control keys. In the center, just above the amount keyboard, are a group of type sectors for the accounting machine, while just to the left of these sectors is located a type basket forthe electric typewriter. .Im-' mediately behind the aforementioned printing mechanism is a rotatable platen, in which accounting forms and/or other record material may be supported, this platen being mountedon a traveling carriage which is movable back and forth across the machine. Behind. the paper carriage is shown that part of the machinecab inet which houses the add-subtract totalizers. At the front of the machine,just to' the left of the typewriter keyboard, is a switch lever for starting and stopping a continuously-running electric motor; which drives the various operating mechanisms of the machine.

'As shown in Figure 35, the operating mecha-l anism of the machine is housed in a cabinet made up of several separate sections, each of which is independently removable in order to yield access to the part of the machine lying thereunder. This cabinet is composed of a front piece 2525i, extending across the front of'the machine and having a central opening, therein for accommodating the keys of the typewriter mechanism. Located on either side of the machine are side plates 20! and 222, immediately behindv which are located additional side plates 253 and 2&4, which cover the sidesand part of the top of the totalizer section of the machine. The top of the totalizer section is further covered by a plate 265, which also extends down overthe rear end thereof and, togetherwith similarly downwardly-extendingportions on side pieces 203 and 2M, serves to cover the rear of the machine. V

The thus-constitutedaccounting machine cabinet is further complemented by keyboard cover plates 256, 201, and 208, which are provided with apertures through which extend the upper ends of barrel-type key caps. To the rear of the keyboard and extending across the machinebetween the side pieces 29I and 252 is an angular strip l of metal 299, which encloses a carriage control mechanism which will be described in detail in a subsequent portion of this description,

FramewwicGligures 1-A andl-B) provided with various ribs, pads, bosses, and cutoutsfor accommodating all of the various structures supported thereon or depending therefrom.

-Mounted on top of the base toward-the front of the machine are a left side frame 254 and a right side frame 2| 5 (see Figures 1-A, 1-3, and 16). Extending between the upper-portion of the side frames and connected thereto is an angle bar 2 it, which serves to support the forward part of the carriage as well as the carriage control 1nech-- 'anisms cooperating therewith. Located behind the angle bar 2|6. andsupported by the side frames is a rail 241 for supporting the rearward 'portion of the carriages Theangle bar 216 is secured t'o the side frames 214 and..2-l5'-by screws 4 250 'is' rotatably mounted on amain cam 218, assho'wn in Figures Q'an'd' 1'7, and the rail 2|? is also secured to the side framesby screws (not shown). The base, the. side. frames, and the cross pieces for supporting the carriage constitute the main framework of themachine, although there are, of course, numerous sub-frames secured to-these main frame elements for supportin'g'the various operating mechanisms of the machine. -These sub-frames will -e described in connection with the mechanisms which they support as the description proceeds.

Motor drive (Figures 3, 6, 22, 23, and '24) The various operating mechanisms of the present machine'are drivenby an electric motor 220 (Figures. 3 and 6).secured to the under side of the base 2| 3.. .As previously mentioned herein, the motor. is adapted to operate continuously while the machine is in use and may be turned on or off by means of a single-pole, single-throw toggle switch 22I (Figure 6), which may be operated'from the front of the machine by means of a lever 222 operably connected therewith. This mechanism will be described in greater detail later herein... A speed controldevice or governor (not shown) is provided on the rear end of the motor shaft for .the purpose of maintaining the speed of the motor essentially constant under the varying load encountered in this type of service. On the front'end of the motor shaft 223 (Figure 3) is'secured a worm 224, which meshes with a worm wheel 225 pinned to a shaft 225, which is'journaled at either end on bearings (not shown) provided in the side walls of a gear casing 221, which is securedby bolts 228 (only one shown) to the frame of the motor 22c and by other :bolts 229 (only one shown in Fige 'ure 3 to the under side of the base 2l3. Hence, whenever the motor is running, the shaft 226 will be drivenv at a reduced rate of speed through the worm 224.and the worm wheel 225. Pinned to theright end of the shaft 228 is a spur gear 240 (Figures 3,16, and '22), which meshes with two other 'spur gears24l (Figure 6) and 242 (Figure 22). The gear MI is secured to a sleeve 243, which is rotatably journaled on a long stud mounted'in the right-hand side of the gear cas ing 221. Secured near the right-hand end of the sleeve 243 is a V-belt pulley indicated generally at 244 and consisting of a right-hand flange 245, which is rigidly secured to the sleeve 243; and a left-hand flange 246, which is constrained to rotate withthe sleeve but is free for limited longitudinal movement thereon. A compression spring 247 surrounds the sleeve 243 and bears against the gear 24! on one end and the left-hand flange'243 on the other end so as to constantly tend to move the left-hand flange to its right-most position, thus tending to take up any play in a V-belt 249, which passes around the pulley 244' and serves to operate the powerdriven roller 485 .(Figure. 1-A) .of the electric typewriter. The sleeve 243 and the parts assembled thereon are retained on the long stud by means of a cap screw 248, which screws into a tapped hole in the endof the stud.

As previously mentioned, the gear 240 meshes :with a gear 242, which is resiliently secured to a notched wheel 250 (Figures 22 and '23) by means of a rubber ring. 25!, which is bonded to the gear 242 and also to a metal ring 252, which is rigidly secured to the wheel 250. The wheel shaft "253 by means .of roller bearings 254. j The'gearj242 and-the notched wheel 250 may be engaged with the main cam shaft 25jjsp; ;a,$
